Council in the event of repair or upgrade the software to check whether the number on the display and the same. This is not a matter of intent, but merely a remote possibility that the technician took the shell wrong during reassembly.

Code: * 3370 # Active EFR. Will be activated after a reboot of the phone.

The EFR (Enhanced Full Rate) is a digital filter which allows a better voice quality than that usually offered by the normal GSM protocol. In general, any conversation is transmitted in a certain frequency band, within which a part, not audible, is completely dedicated to sending data and the error control.

The new technology of data compression ASELP (Algebraic Code Excitation Linear Prediction) is successful, the same number of bits used by the previous mode (which is called LPC-RPE Linear Prediction Coding with Regular Pulse Excitation), to improve voice quality. The result is a tangible improvement in the quality of the conversation, which in theory could approach that of the fixed network.

So to improve the audio quality of your phone you can activate the 'Enhanced Full Rate (EFR) there is a correspondence between the increase in sound quality on the GSM network and a growing consumption of energy used by your mobile phone. If you decide to activate the 'Enhanced Full Rate points out that the autonomy of your battery will decrease by 5%.

If you wish to disable the 'Enhanced Full Rate uses:

Code: # 3370 # EFR off. Will be de-activated after a reboot of the phone.

Code: * 4720 # Half Full Rate active. Will be activated after a reboot of the phone

The HR (Half Rate), as the name implies, allows you to send a signal using only half the available bandwidth. Each conversation is normally coded 13Kb / s. In the moment in which the HR is activated, the encoding is brought to 6.5 Kb / s. The main purpose of the whole is the doubling of the channels usable by the user, with enormous advantages in the case of network congestion.

A happy consequence of the lower bit rate that is a considerable saving the battery of the phone, an increase of almost 50% of autonomy in conversation. The tradeoff, in this case, is a small reduction in voice quality. Very useful when the efficiency of your battery has been drastically reduced!

If you wish to disable the 'half rate using:

Code: # 4720 # off HR. Will be de-activated after a reboot of the phone.

What is IMEI?

It 'a code of 15 digits that can uniquely identify a mobile phone. IMEI stands for "International Mobile Equipment Identity Number", it is placed, usually on a label underneath the battery and for most phones, you can make it appear on the display by typing the code * # 06 #

For users TIM, codes for Twin Card
* 122 # to see which card is currently active on the phone if the master or slave
* 133 # to automatically change the cards from Master to Slave or vice versa
